Deal has changed. Price is now 20.99. However, at that price it still beats other retailers, given this ships free.

$20.99 is the price without the code. $5 off with code.

I have one of these. It was a lot of fun plugging it in at various spots to see how much power was being used. However, it it bulky and requires a lot of space to plug it in. I think there was a different model that came with a short extension cord you could use so you wouldn't have to try to plug this directly into the socket. You may want to make sure you have a spare extension cord handy on the day you plan to use this.
